Attention span: 6/10 Lacks a level editor and uses a repetative track.Controls: 10/10 Good selections for the operations.Implementation: 9/10 Awesome 3D graphics. A random track would be good.Overall: 8/10 A game you will get tired of quickly.

Plain Jump is a game where you are a marble and must avoid falling off of the moving track. If you are familiar with SkyRoads for the computer, it is similar to that. You use the arrow keys to move left and right, accelerate, and stop. The 2nd key is used to jump. The game supports multiple levels, and five levels come with the game.

There is no level editor, and once the user gets bored with the five levels they will delete them. The repetative nature of the tracks means that the user gets bored rather quickly. The graphics, though, are great. I would recommend a random track option so that the users would be kept on their toes.
